About Me

The Journey

My journey into programming began in 2019, sparked by a friend's recommendation to take Harvard's CS50 course. What started as self-taught curiosity quickly evolved into a dedicated career. I formalized this passion by pursuing a Software Engineering degree, consistently pushing myself to learn beyond the classroom.

Since then, I've had the privilege of training under Google's Bangkit Academy, building government application systems, and developing SaaS platforms for IT companies. Today, as a Software Engineer, my focus is on delivering cutting-edge technologies while maintaining high maintainability and scalability.

Outside of my core work, I actively take on freelance projects and continuously learn and experiment with new technologies.
